Overview of this book

By learning TypeScript, you can start writing cleaner, more readable code that’s easier to understand and less likely to contain bugs. What’s not to like? It’s certainly an appealing prospect, but learning a new language can be challenging, and it’s not always easy to know where to begin. This book is the perfect place to start. It provides the ideal platform for JavaScript programmers to practice writing eloquent, productive TypeScript code. Unlike many theory-heavy books, The TypeScript Workshop balances clear explanations with opportunities for hands-on practice. You’ll quickly be up and running building functional websites, without having to wade through pages and pages of history and dull, dry fluff. Guided exercises clearly demonstrate how key concepts are used in the real world, and each chapter is rounded off with an activity that challenges you to apply your new knowledge in the context of a realistic scenario. Whether you’re a hobbyist eager to get cracking on your next project, or a professional developer looking to unlock your next promotion, pick up a copy and make a start! Whatever your motivation, by the end of this book, you’ll have the confidence and understanding to make it happen with TypeScript.

Even object-oriented programming paradigms depend heavily on functions as a basic building block of business logic.

Functions, sometimes called routines or methods, are part of every high-level programming language. The ability to reuse segments of code is critical, but functions provide an even more important role than that in that they can be given different arguments, or variables, to act against and produce different results. Writing good functions is the difference between a good program and a great one. You first need to start by learning the syntax before thinking about crafting a good function by considering what arguments it should take and what it should produce.

In this chapter, we will cover three different ways to create functions...
